9 Astonishing Facts About Hiccups That Will Surprise And Inform You
The Noise Hiccups Make

All Healthy News
No medical training is needed to identify a case of hiccups because one of the most obvious signs of this condition is the noise it makes. The 'hic' noise is an involuntary sound produced by a reflex that is triggered when the throat closes in response to excess air in the body's breathing passage. This process takes approximately 0.25 to 0.35 seconds and begins when the diaphragm contracts and the vocal cords reflexively close. The sound varies in volume and frequency across people. The word 'hiccup' is an example of onomatopoeia, a property of words that imitate sounds, used in comics, cartoons, and pop art.
Everyone Can Get Them

It is sometimes believed that people who belong to certain demographic, racial, or geographic populations do not suffer from hiccups. However, this belief is false. Anyone can get hiccups regardless of race, gender, or age. Even fetuses can develop symptoms of hiccups while in the womb. This happens primarily during the third trimester when the baby is growing and developing rapidly before its big arrival. Hiccups can also affect household pets, such as cats or dogs, with some folks believing they can signify an impending growth spurt in these animals. In sum, any animal with an evolved breathing system can get hiccups. Hiccups do not discriminate.
